Heads-up for anyone who hit 502 Bad Gateway on text calls in that window: **What happened:** Every text reverse-RPC (sampling/createMessage, agent/complete) returned HTTP 502, while image/generate succeeded over the exact same auth + reverse-RPC + Cloudflare path. GET / and /api/v1/health were both 200. **Root cause:** A brief outage of the **text-model upstream** on anna.partners. The gateway couldn’t get a valid response from the LLM completion backend → 502. The image backend is a separate upstream and stayed healthy. **Why it’s not your app / auth / SDK:** Image generation working over the identical path rules out auth, grants, protocol, the SDK, and Cloudflare-in-general. The errors are upstream signals: agent/complete → -32046 (AGENT\_ERR\_PROVIDER\_ERROR — catch-all incl. /copilot/app/complete returning 5xx), and sampling → -32000 wrapping the raw HTTP 502. **Good news:** No quota leak — the throw-away session is always torn down in finally, so retrying is safe. **What to do:** Retry (it was a ~4-minute window and likely self-healed). If it persists, escalate to whoever runs the anna.partners text-model gateway with the timestamp window + the “text 502 / image OK” contrast. App correctness (e.g. for hackathon review) can be re-verified once the text upstream is back. ---

Hi @YuntianBi! 👋 Huge thanks for such a sharp, well-structured write-up — the “text 502 / image OK” contrast and the throw-away-session teardown detail are exactly the kind of signal that makes triage fast. 🙌 This is really helpful for the whole community. 💛 You’re right that a brief text-upstream blip can cause this. To make sure we pin down the _exact_ cause (a short self-healing outage looks identical on the surface to a couple of other issues 🔍), could you share a bit more when you have a moment? A few targeted details go a long way: ## What would help us localize it fast 🛠 1. **Timestamp window (with timezone) 🕒** e.g. `2026-06-18 14:32–14:36 UTC` — lets us line it up against upstream/gateway logs for that exact window. 2. **Which model was selected 🧩** The specific model name in the picker at failure time (e.g. `qwen3.7-plus`, `google/gemini-3-flash-preview`, or the free `Gemma 4 E4B-it`). This matters a lot — a single-model failure vs. all-models failure points to very different root causes. 3. **Was it all text models, or just one? 🎯** Did switching to another model (e.g. from Gemma → a Qwen/Gemini option) also 502, or did it recover? “Every model failed” vs. “only one failed” is the single most useful disambiguator. 4. **The raw error body / code 📄** The exact string you saw, e.g.: 5. **Path contrast you already noticed 🔀** You nailed this one — confirming `image.generate` succeeded on the same auth/reverse-RPC/Cloudflare path in the _same_ window is gold for ruling out auth/SDK/protocol. 🏆 6. **Duration & retry behavior ⏱** Was it a short window that self-healed on retry (sounds like ~4 min here), or persistent and reproducible every time? Self-healing → likely a transient upstream blip; persistent + reproducible → more likely something deterministic we can patch. ## Example of an ideal report 📋 > **When:** 2026-06-18 14:32–14:36 UTC > **Model:** `Gemma 4 E4B-it` > **Scope:** only Gemma failed; `qwen3.7-plus` worked in the same window > **Error:** `404 — The model 'gemma-...' does not exist` > **Contrast:** `image.generate` OK on the same path > **Pattern:** persistent, reproduced every retry That single block usually tells us whether it’s a transient upstream outage, a model that’s been rotated/retired, or a code-path issue — and gets you a precise fix or all-clear much faster. 🚀 Thanks again for being so thorough and community-minded — drop the details whenever you can and we’ll dig right in! Excited to keep your builds running smoothly. 🎬✨ Happy building! 💛
